The document discusses solar and lunar eclipses. It explains that a solar eclipse occurs when the moon passes between the Earth and the sun, casting its shadow on parts of Earth. A lunar eclipse happens when Earth passes between the sun and moon, casting its shadow on the moon. There are three types of solar eclipses: partial, annular, and total, depending on the alignment of the sun, moon, and Earth. During a solar or lunar eclipse, the moon's shadow on Earth or Earth's shadow on the moon can include the umbra, antumbra, or penumbra regions.

1. Solar
Eclipse
OBJECTIVE: Explain how
solar and lunar eclipses
occur using models
Lunar
Eclipse

2. describe the
arrangement of
the Sun, Earth,
and Moon during
a solar and lunar
eclipse
When does lunar
and solar eclipse
occurs.
The three major
parts during
solar eclipse
After today's lesson,
you should be able to:
The three kinds
of solar and
lunar eclipses.

3. Have you
witnessed
a solar or lunar
eclipse?

4. What Do we
mean by
Eclipse?

5. What Do we
mean by
Eclipse?
ECLIPSE is an stronomical event that occurs when
one heavenly body such as the moon or a planet
moves blocks light on to another. There are two types
of eclipses on Earth: A solar and a lunar eclipse

6. Solar Eclipse
A solar eclipse occurs
when the moon moves in
between the earth and the
sun causing a shadow of a
moon to fall on certain
portions of the earth.
There are three major
parts during a solar
Eclipse, These are: umbra,
antumbra and penumbra

7. UMBRA
The small and very dark shadow created during a
solar eclipse is known as the umbra. The umbra is
the portion of the moon shadow when the moon
completely covers the sun. This is when the total
solar eclipse occurs which the sun cannot totally be
seen.
Three major parts
during Solar Eclipse

8. UMBRA
The small and very dark shadow created during a solar eclipse is
known as the umbra. The umbra is the portion of the moon shadow
when the moon completely covers the sun. This is when the total
solar eclipse occurs which the sun cannot totally be seen.
Three major parts
during Solar Eclipse
ANTUMBRA
The antumbra is the area
beyond the umbra, where the
moon is completely in front of
the sun but does not cover
the entire sun. The antumbra
is when the outline of the sun
can be seen around the
shadow of the moon, hence
the occurrence of the annular
solar eclipse.

9. UMBRA
The small and very dark shadow created during a solar eclipse is
known as the umbra. The umbra is the portion of the moon shadow
when the moon completely covers the sun. This is when the total
solar eclipse occurs which the sun cannot totally be seen.
Three major parts
during Solar Eclipse
PENUMBRA
The penumbra is the area of the
shadow when only the portion of the
moon is in front of the sun. This
shadow is larger and relatively lighter
than the umbra. This is when the
partial solar eclipse happens which
only a small part of the sun can be
seen.
ANTUMBRA
The antumbra is the area
beyond the umbra, where the
moon is completely in front of
the sun but does not cover
the entire sun. The antumbra
is when the outline of the sun
can be seen around the
shadow of the moon, hence
the occurrence of the annular
solar eclipse.

10. The three types of
Solar Eclipses

11. A small portion of the
Sun can still be seen.
The Sun, Moon, and Earth are not exactly aligned.
Partial

12. Annular
The Moon does not completely
block the Sun but creates a
ring around the Moon.
The Sun, Moon, and Earth are not exactly aligned.

13. Total
The Moon completely
blocks the Sun.
The Sun, Moon, and Earth are directly in line.

14. Lunar Eclipse
A lunar eclipse occurs
when the earth is in
between the moon
and the sun, blocking
the sun's
light from reaching
the moon.

15. Solar Eclipse
Sun
Sun's Rays
Blue light is scattered
by Earth's Atmosphere
umbra
Red Light gets refracted passes
through the atmosphere, and
falls onto the moon penumbra

16. Lunar Eclipse
umbra
Penumbra
The earth creates two shadows on the moon during
lunar eclipse. These are umbra and penumbra.

17. Lunar Eclipse
umbra
Penumbra
The Penumbral lunar eclipse is when the moon travels in a penumbra, and
the moon appears slightly darker than the usual. When the part of the
moon is in the penumbra and the other part of the moon is in the umbra,
the partial lunar eclipse occurs.

18. Lunar Eclipse
Total lunar Eclipse
Partial lunar eclipse
Penumbra Lunar
Eclipse
sunlight
Red moon
The total lunar eclipse
happens when the moon
travels to the umbra. During
total lunar eclipse, earth
completely blocks any
sunlight from reaching the
moon and appears red due to
the inward refraction of the
red waves from the earth's
atmosphere
towards the moon.
